Dual container



DUAL QONTAINER Filed June 10, 1952 Patented Nov. 6, 1934 T AT ES Application June 10, 1932, Serial No. 616,567 In Germany September 18, 1931 10 Claims.

This invention relates toimprovements in devices for storing incompatible materials and for bringing such materials into contact when it is desired to discharge the intermingled substances at some suitable point.

While the device has many uses, it is especially adapted for separately storing two mixtures which will produce a medicated-foam when they are united, and which may be used to apply the foam when so produced for treatment of vaginal diseases, in female hygiene, and similar purposes.

One of the objects of the invention is to provide a container comprising a tube for the storage of one substance, and a collapsible bulb for the storage of the second substance; these parts being relatively movable so that the two substances may be brought together in the container when the combination is to be applied.

Another object is to furnish a device of this kind in which the movement of one part relatively to the other will automatically cause at least a portion of the substance of the tube to enter the bulb for admixture with the substance contained in the bulb.

25 With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists inthe novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing,

Fig. l is a longitudinal sectional view of a complete package with the incompatible substances omitted.

Fig. 2 is a similar view after the wrapper has been removed, and after the tube has been shifted relatively to the bulb for the purpose of bringing the two substances into intermingled relation.

Fig. 3 is a view like Fig. 2, but illustrating the bulb in collapsed condition for the purpose of ejecting the intermingled substances through the tube which functions as a douche nozzle.

Fig. 4 is a top plan view of a package containing a plurality of the devices.

Referring to Figs. 1, 2 and 3, 5 designates a tube of any suitable relatively stiff material, such as glass or celluloid, provided at its outer end with a head 6 which may be closed by a removable cap 7 after one of two incompatible substances has 50' been placed in the tube.

The opposite end of the tube is also closed by any suitable type of plug 8. The latter plug may be made of rubber and be vulcanized or otherwise suitably secured to a bulb 9 which surrounds the lower end of the tube and is to contain the other one of the two incompatible substances. When the parts are in the position shown in Fig. 1, it will be noted that a collar 10 at the upper end of the bulb frictionally grips the outer surface of the tube, and the bulb can be filled by injecting the second substance into the bulb through the neck thus formed, and after the bulb has been filled, a spring metal clip 11 or the like can be placed in embracing position on the collar for clamping the latter to the tube.

It will be noted that when the two substances are to be brought together, the bulb 9 is slid downwardly on the tube for the purpose of re-- moving the plug 8 from the lower end of the tube, so as to place the interior of the tube in communication with the interior of the bulb, but normally, such movement is to be prevented, as it is absolutely necessary to keep the two substances segregated from one another. Therefore, for the purpose of holding the parts in collapsed or storage position, a wrapper 12 of any suitable material, such as cellophane paper, may be placed about the device. The ends of this wrapper will abut against the ends of the device and prevent the tube from shifting axially relatively to the bulb.

When the device is to be placed in use, the wrapper 12 is removed, and then the bulb is pulled downwardly on the tube, as shown in Fig. 2, until the collar 10 comes to rest against a bead 13 at the lower end of the tube. Before thus moving the parts, the cap 7 will be removed, and consequently, atmospheric pressure will cause the substance within the tube to move such substance into the void created by the relative movement of the parts, with the result that the two substances will now be brought together within the bulb for the purpose of forming the medicated mixture or foam. Now, if the tube is used as a nozzle or applicator, and the device is inserted in a vaginal or other cavity to be treated, and the bulb is compressed, as shown in Fig. 3, the medicated foam will be ejected at the point where the combined substances are to be applied.

It is obvious that various means may be employed to normally hold the tube member and bulb member in the relative positions shown in Fig. l, and instead of using a wrapper 12, a number of the devices may be placed in a box 14, as shown in Fig. 4. Such box may have a strip of cardboard 15 secured to the caps 7a of a number of tubes, and when the heads of the tubes 5a are inserted in these caps, the plugged lower ends 8a of the bulbs can be brought into frictional engagement with the wall 16 of the box, which is opposite the wall 17 against which the strip 15 abuts. When it is desired to remove one of the devices from the box, its bulb 9a may be lifted until the bulb clears the upper edge of the box, and then the head of the tube can be withdrawn from the cap 7a. Then the withdrawn device is ready for use.

From the foregoing it is believed that the construction, operation and advantages of the invention may be readily, understood, and it is apparent that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.

What is claimed and desired to be secured by Letters Patent is:

1. A device of the kind described, comprising a relatively movable tube member and bulb member, said members being adapted to contain incompatible substances, and a plug for one of said members secured to the other member and normally segregating the interior of one member from the interior of the other member.

2. A device of the kind described, comprising a relatively movable tube member and bulb member, said members being adapted to contain incompatible substances, a plug for one of said members secured to the other member and normally segregating the interior of one member from the interior of the other member, and a re-. movable cap for the tube member.

3. A device of the kind described, comprising a relatively movable tube member and bulb member, said members being adapted to contain incompatible substances, a plug for one of said members secured to the other member and normally segregating the interior of one member from the interior of the other member, a removable cap for the tube member, and means for normally preventing the cap from moving away from said plug.

4. A device of the kind described, comprising a relatively movable tube member and bulb member, said members being adapted to contain incompatible substances, a plug for one of said members secured to the other member and normally segregating the interior of one member from the interior of the other member, and means for normally preventing said parts from moving relatively to one another.

5. A device of the kind described, comprising "a relatively movable tube member and bulb 'member, said members being adapted to contain in compatible substances, a plug for one of said members secured to the other member and normally segregating the interior of one member from the interior of the other member, and a wrapper enclosing said members and normally preventing relative movement of said members.
